  3. 12. The Holocene Spread of Spruce in Scandinavia

    Författare :Thomas Giesecke; Keith Bennett; Richard Bradshaw; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quaternary geology; Picea abies; pollen analyses; tree migration; population dynamics; Kvartärgeologi; Quaternary geology; Kvartärgeologi;

    Sammanfattning : The Holocene spread of Picea abies in Scandinavia provides an excellent opportunity for detailed study of the dynamics of tree spread and population expansion. Early- and mid-Holocene macrofossil evidence for the presence of Picea abies in Scandinavia has questioned traditional interpretations of the timing and direction of its spread. LÄS MER

    Sammanfattning : Norway spruce [Picea abies (L.) Karst.] is a main tree species in European forests and is important both ecologically and economically. The root rot fungus Heterobasidion annosum sensu lato (s. LÄS MER

  5. 14. Novel resources enabling comparative regulomics in forest tree species

    Författare :David Sundell; Torgeir Hvidsten; Klaas Vandepoele; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Comparative genomics; Web resource; Wood development; RNA-Seq; Forestry; Lignocellulose; Regulomics; High-spatial resolution; Populus tremula; Picea abies; Orthology.; biology; biologi; molekylär bioteknik inst f nat vet biokemi ; molecular biotechnology dept of biochem ;

    Sammanfattning : Lignocellulosic plants are the most abundant source of terrestrial biomass and are one of the potential sources of renewable energy that can replace the use of fossil fuels. For a country such as Sweden, where the forest industry accounts for 10% of the total export, there would be large economical benefits associated with increased biomass yield. LÄS MER

  7. 15. Conifer Evolution, from Demography and Local Adaptation to Evolutionary Rates : Examples from the Picea genus

    Författare :Jun Chen; Martin Lascoux; Ulf Lagercrantz; Matt Olson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Speciation; Demographics; clinal variation; convergent evolution; transcriptome; small regulatory RNA; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Evolutionary process can be inferred at three different levels: the species level, the population level and the molecular level. In this thesis, I applied approaches at these three levels and aimed to get a comprehensive picture of conifer evolution, from speciation and demography to geographic variation and local adaptation, and then to the molecular evolution of proteins and small regulatory RNAs.
